Light Sequence Determination: Notes
If Quick Checks did not isolate symptom, it is necessary to check operation of warning lights. The system uses 2 warning lights, the Red "BRAKE" warning light and an Amber "Check Anti-Lock Brakes" light. By observing when these lights come on, specific components and sub-systems of the brake system may be isolated as likely causes of a system malfunction.
Each light sequence illustration is divided into seven areas which represent vehicle status, with the behavior of the "BRAKE" and "Check Anti-Lock Brakes" lights represented in the horizontal rows below the vehicle status headers. See Fig 1 .
"BRAKE" and "Check Anti-Lock Brakes" light status is indicated by the shaded areas in the horizontal rows below each vehicle status header. Right-hand diagonal shading indicates illumination of the "Check Anti-Lock Brakes" light, while a left-hand diagonal shading indicates a lit "BRAKE" light. A vehicle status block which is not entirely shaded means that the light is on only for part of the test period. See Fig 1 .
